Sealing performance: Ball valves have two types of sealing: elastic seals and metal seals. Metal seals usually have longer life than elastic seals, but elastic seals have the disadvantage of being limited by temperature.
Flow control: When the ball valve is fully opened, the resistance caused by the thickness of the butterfly plate is small, and it has good flow control characteristics.
Applicable media: Ball valves can be used to control a variety of media, including water, steam, oil, nitric acid, acetic acid, oxidizing media, urea, etc.
Connection method: Ball valves have various connection methods, including flanges, butt welding, threads, socket welding, etc.
Temperature and pressure range: Ball valves are suitable for a wide temperature range from -196℃ to 540℃, and have a variety of nominal pressure grades.
Drive mode: The ball valve can be driven by manual, worm gear drive, pneumatic, electric, hydraulic, gas-liquid linkage, electro-hydraulic linkage and other methods.
Material selection: The valve body material of the ball valve is diverse, including WCB, ZG1Cr18Ni9Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti, etc., which are suitable for different media and working environments.
Troubleshooting: For the wear problem of the ball valve, wear-resistant materials such as ceramic materials and polymer composite materials can be used for repair.
The simple design, efficient operation and wide range of material selection of the ball valve make it an indispensable flow control device in industrial applications.
The ball valve is not only suitable for general industrial use, but also for demanding cut-off conditions, such as petroleum, chemical industry, urban water supply and drainage, etc. In addition, information such as the working principle, model specifications and structural diagram of the ball valve can also help to select a suitable ball valve in actual work.

A butterfly valve is a disc-shaped valve whose closing part (valve disc or butterfly plate) rotates around the valve shaft to open and close. It is mainly used for cutting off and throttling on pipelines. The following are some key features and applications of butterfly valves:

Simple structure: The butterfly valve consists of a valve body, a valve stem, a butterfly plate and a sealing ring. It has a simple structure, small size and light weight.
Easy to operate: The angle from full opening to full closing of the butterfly valve is usually less than 90°, and it opens and closes quickly, is easy to operate, and has a small driving torque.
Good fluid control characteristics: Butterfly valves are mainly used to cut off, distribute and change the flow direction of the medium on the pipeline, and have good flow control characteristics.
Sealing performance: Butterfly valves have two sealing types: elastic sealing and metal sealing. The sealing ring of the elastic sealing valve can be embedded in the valve body or attached to the periphery of the butterfly plate.
Wide application: Butterfly valves are widely used in petroleum, chemical, metallurgy, hydropower and other fields, and are suitable for a variety of media, including water, oil, gas, water-solid two-phase and gas-solid two-phase flow.
Temperature and pressure range: Butterfly valves can be used in different temperature and pressure ranges, and are suitable for a variety of working conditions from low temperature to high temperature, low pressure to high pressure.
Various connection methods: The connection methods of butterfly valves include flange connection, clamp connection, butt welding connection and lug clamp connection.
Drive mode: The drive mode of butterfly valves can be manual, electric, pneumatic, hydraulic, electro-hydraulic linkage, etc., which can realize remote control and automatic operation.
Suitable for large-diameter valves: The structural principle of butterfly valves is particularly suitable for making large-diameter valves, with small flow resistance and good adjustment performance.
Special design: For special working conditions, such as high temperature, high pressure, strong corrosion and other conditions, butterfly valves have special designs, such as three-eccentric metal hard seal butterfly valves, to meet different industrial application requirements.

Butterfly valves play an important role in the field of industrial automation control due to their simple structure, convenient operation and good fluid control characteristics.

The gate valve is an important industrial valve. Its opening and closing parts are gates, which control the flow of fluids by lifting and lowering the gates. Here are some key features and applications of gate valves:

Working principle: The gate valve controls the flow of fluids by the vertical movement of the gate. The fluid channel opens when the gate rises and closes when the gate falls.
Structural features: The gate valve has a simple structure and is usually composed of valve body, valve cover, valve stem, gate and other components.
Sealing performance: The sealing surface of the gate valve can be wedge-shaped or parallel, and the wedge-shaped gate can be rigid or elastic to improve the sealing performance.
Fluid resistance: Since the channel of the gate valve is linear, the fluid resistance is small, which is suitable for large flow fluid control.
Effortless opening and closing: Compared with the stop valve, the opening and closing of the gate valve is more labor-saving because the movement direction of the gate is perpendicular to the flow direction of the medium.
Installation direction: The gate valve medium can flow in any direction on both sides, which is easy to install.
Maintenance: The maintenance of the gate valve is relatively simple, but professional repairs may be required after the sealing surface is worn.
Application: Gate valves are widely used in tap water, sewage treatment, chemical industry, papermaking, food and other industries, and are suitable for occasions that require frequent opening and closing or flow adjustment.
Various types: Gate valves are of various types, including wedge-type gate valves, parallel gate valves, open-stem and concealed-stem gate valves, etc.
Advantages: The advantages of gate valves include low flow resistance, simple structure, good sealing, easy operation and strong adaptability.
Disadvantages: The disadvantages of gate valves may include wear on the sealing surface, large external dimensions, a certain amount of space required for opening, and complex structure.
As a shut-off valve, gate valves play an important role in industrial process control and are suitable for a variety of fluid control occasions.

The gate valve is an important industrial valve. Its enabled and closed parts are the gate, which controls the flow of fluid through the lifting of the gate. The following are some key features and applications of the gate valve:

Working principle: The lock valve controls the flow of the fluid through the vertical movement of the gate. When the slice rises, the fluid channel is opened, and the fluid channel is closed when the gate falls.
